Nexus Calc's camera handles the hard part. But the intelligence behind it? That's up to you. Upload any API key and run the AI model of your choice — directly on your device.
The built-in 5MP mini camera reads handwritten notes, printed textbooks, and whiteboard diagrams. No typing required — just aim and press.
AI processing via hotspot or Wi-Fi. Results appear on screen the moment you snap.
Export full solution sets via USB or Bluetooth. PDF, CSV, or plain text — your format, your workflow.
The 70° FOV lens captures textbook pages and whiteboards clearly in a single frame — nothing gets cut off.
Every solution broken into numbered steps — so you understand the method, not just the answer.
Point the built-in camera at any problem — handwritten notes, textbook pages, or a whiteboard — and press the snap button. It works at any angle.
The AI identifies the problem type, selects the right method, and computes the full solution with step-by-step working — requires an internet connection via hotspot or Wi-Fi.
Results appear directly on the TI-84's stock screen. The answer and full step-by-step working show up exactly where you'd expect — no extra hardware, no separate display.
Point the camera. Get the answer. Every step shown — algebra, calculus, chemistry, physics. No subscription ever.
